“…In this way, it can be seen that the superconducting parameters of the Bi-2212 system are improved. In particular, doping with elements belonging to Group-1A metals such as Li, Na, and K has been observed to improve significantly critical current densities (Jc) of the Bi-2212 system [13,14] In this study, it was aimed to increase Jc values by adding Li at the rates of 0, 0.05, 0.10, 0.15, and 0.20 instead of Cu in the Bi-2212 system. With this objective in mind, Li-containing Bi-2212 samples were prepared by the classical solid state method and their characteristic properties were revealed by Scanning Electron Microscopy (SEM), magnetization versus temperature (M-T) and magnetization versus magnetic field measurements (M-H).…”

This study is about examining the effect of lithium substitution for the copper site of the Bi-2212 superconductor on microstructural, magnetic hysteresis and critical current densities. Superconducting samples given with the nominal formula Bi2Sr2CaCu2-xLixO8+δ where x= 0, 0.05, 0.10, 0.15, and 0.20 were produced by the classical solid state reaction method due to reasons such as ease, repeatability and low cost. To determine the microstructural properties of the samples, SEM photographs at 10 kX were taken and with the increase in Li-content, an evolution from randomly platelet-shaped grains to rectangular prism-shaped grains was observed. Critical transition temperature (Tc) values of the samples increased with Li-level in Bi-2212 observed from M-T measurements. Additionally, it is revealed from M-H measurements that the area of the hysteresis curves expanded with the increase of Li-content . Accordingly, values of remanent magnetization (Mr) and critical current density (Jc) of Bi-2212 samples were found to be increase with Li-substitution for Cu-site.
